[PATCH] cg-object-id: use git-rev-parse(1) for date parsing

From: Jonas Fonseca <fonseca@diku.dk>
Date: Dec 7, 2005, 21:40 UTC
Message-ID: <20051207214013.GD25890@diku.dk>

Using the --until switch, git-rev-parse(1) will first be given the ID. If it cannot make sense of the ID fallback to using date(1).

Signed-off-by: Jonas Fonseca <fonseca@diku.dk>

 The mixing of date parsing behaviours might be a little questionable,
 but it's good to stay compatible with git.
